Tevin Bush has been known as a jack of all trades for the Landry-Walker offense for the past two seasons, but they asked him to do something he’s never done Saturday night.

With quarterback Keytaon Thompson going down with an injury in the fourth quarter, the junior running back had to make two big plays as the signal-caller for the Charging Bucs (2-1) and helped push them to a hard-fought 13-6 win over St. Augustine at Tad Gormley Stadium.

“I played quarterback in park ball, so it was natural transition,” Bush said. “I just wanted to do whatever it took to help the team get the win.”

With Bush at quarterback, Landry-Walker had the ball late in the game clinging to a 7-6 lead and was fighting to run the clock out to secure the win.

Bush kept the Charging Bucs drive alive with a 9-yard pass on one third down and a 25-yard run on another, before Malik Arnold broke a 55-yard touchdown run to increase the Landry-Walker lead to 13-6 with 3:05 left in the game.

Landry-Walker coach Emmanuel Powell said the injury was a sprained ankle and Thompson should be back for next week’s game.

“Every win is a big,” Powell said. “My hats off to the kids. They fought hard throughout and did what it took to come out with the win.”

Both teams struggled to get out of their own way in an ugly first half that included six punts, 16 penalties and two lost fumbles — both by St. Aug (0-3).

The only score of the first half came after Thompson hit wide receiver Kahlil Williams for a 51-yard strike at the end of the first quarter.

Four plays into the second, Bush dove into the end zone from a yard out to give Landry-Walker a 7-0 lead.

The Charging Bucs defense stopped St. Aug from converting long drives into points several times and held their 7-0 lead into halftime.

After failing on three different occasions to convert trips into the Landry-Walker red zone into points, the Purple Knights found a way to get some points on the board at the end of the third quarter — with a little assistance from Landry-Walker.

The Purple Knights thought they were stuffed in the red zone once again after an incomplete pass on a fourth down, but the Charging Bucs were called for roughing the passer, extending the drive.

Three plays later, St. Aug quarterback Justice McCoy pushed his way into the end zone from one yard out.

After failing on the two-point conversion, Landry-Walker remained ahead with a 7-6 lead with 1:35 left in the third.

“This game was hard-fought throughout and I just wanted to come through at the end for my brother,” Bush said, referring to Thompson. “It wasn’t pretty, but a win is a win.”

Landry-Walker will play in its first District 8-5A game next week on the road against Chalmette, while St. Aug will open up Catholic League-play against defending Division I state champion Jesuit.
